Definitions

  • the present invention relates to a wiper blade and a manufacturing method for producing such a wiper blade.
  • Windscreen wiper blades are to adapt to the contour of the windshield of a motor vehicle and retain their flexibility even at different temperatures. Windscreen wiper blades are therefore conventionally made of elastomeric profiles and rubber materials such as natural rubber and chloroprene rubber. In addition, wiper blades can be made of silicone rubber or polyurethane rubber.
  • elastomers Compared with materials such as glass or plastic, elastomers have a high coefficient of sliding friction, so that in the case of a vertical contact force on the elastomeric profile, such as a windshield wiper blade on the surface of a glass windshield, a multiple of the horizontal force application force must be applied.
  • coatings with a low coefficient of friction are conventionally used.
  • these coatings may consist entirely of graphite or include graphite and other components such as fillers, secondary lubricants, polymeric binders and crosslinking agents.
  • the sliding properties are usually due to the application of soft, particulate fillers, such as graphite or molybdenum sulfide, on the elastomer surface scored the wiper blade.
  • soft, particulate fillers such as graphite or molybdenum sulfide
  • efficient sliding is usually achieved by coatings comprising a soft, particulate filler in a relatively high amount, for example greater than 60 volume percent, preferably greater than 85 volume percent, based on the total coating.
  • a processing step is, for example, fitting the coated wiper element in the wiper blade frame or attaching the wiper blade to the wiper arms of a motor vehicle.
  • graphite may be transferred from the coated rubber element to other parts of the wiper blade, such as the spoiler area, resulting in soiling which makes the wiper blade sold for aesthetic reasons.
  • coated rubber element may also transfer graphite to different areas of the production line, such as conveyors and conveyor accessories.
  • graphite may be transferred to the windshield, resulting in dark streaks on some areas of the windshield, particularly the so-called flip-over area in which the wiper blade makes a change of direction.
  • the present invention is wiper blade, for example an elastomeric wiper blade, in particular for a windshield wiper, comprising an elastomeric profile, a base layer which at least partially covers the surface of the elastomeric profile and at least one particulate lubricant and a basecoat-covering, water-soluble and / or water-dispersible topcoat.
  • the double layer structure on the wiper blade has the advantage that the upper layer, referred to as the cover layer, acts as a barrier and immobilizes the lubricant particles of the lower layer, referred to as the base layer.
  • the base layer may therefore comprise a high level of particulate lubricant, such as graphite, while still avoiding lubricant particles from contact when handling the wiper blade on objects or persons, such as a worker's hand, another part of the wiper blade, or the windshield , in particular during the processing, transport, packaging, storage and first use of a new wiper blade.
  • a high proportion of particulate lubricant can advantageously ensure a low coefficient of friction of the base layer.
  • the present invention is based, in particular, on the principle that the cover layer assumes only a temporary shielding function and dissolves during the first wiping phase of a new wiper blade and the lubricant-containing base layer ensures low friction during wiping of the windshield.
  • the base layer is preferably designed such that it has a low coefficient of friction and / or ensures good adhesion to the elastomer profile.
  • the base layer may contain ⁇ 30 wt% to ⁇ 100 wt%, in particular ⁇ 45 wt% to ⁇ 95 wt%, preferably ⁇ 60 wt% to ⁇ 90 wt%, based on the total weight of the Base layer, to include lubricants.
  • the lubricant is selected from the group consisting of graphite, molybdenum sulfide, polyamide, Polyethylene, polytetrafluoroethylene (PTFE), micro glass beads, wax and mixtures thereof.
  • the lubricant may be graphite.
  • the base layer may consist entirely of the lubricant as well as of a lubricant-additive mixture.
  • the base layer may comprise at least one polymeric binder.
  • the base layer may comprise at least one non-water-soluble, polymeric binder and / or non-water-soluble, crosslinked, polymeric binder
  • the cover layer is preferably configured to remain intact during handling, processing, packaging, storage, and the initial wiping phase of a new wiper blade.
  • the cover layer comprises a water-soluble and / or water-dispersible, in particular hydrophilic, polymeric binder.
  • the binder is film-forming.
  • the binder of the cover layer is not crosslinked. In this way, a rapid and complete dissolution of the cover layer by water droplets, especially in the initial wiping phase when wiping a windshield, guaranteed and deposits of the binder can be prevented.
  • the cover layer in the context of a further embodiment of the present invention may comprise crosslinked binders.
  • the topcoat may comprise ⁇ 10 wt% to ⁇ 100 wt%, in particular ⁇ 50 wt% to ⁇ 100 wt%, preferably ⁇ 80 wt% to ⁇ 100 wt%, based on the total weight of the topcoat, of crosslinked binders.
  • the binder of the cover layer can be crosslinked by a, in particular chemical, crosslinking agent. Partial crosslinking of the binder of the cover layer can advantageously result in improved immobilization of the lubricant particles in the upper region of the base layer.
  • a can controlled dissolution of the top layer can be achieved, which leads to a delay or slowing down the lubricant delivery of the base layer.
  • a delayed or slowed lubricant delivery in turn has the advantage that too high a deposit of lubricant in the form of strip-like deposits in the flip-over area of the windshield can be prevented.
  • the cover layer has non-stick properties. These may for example result from the properties of the binder of the topcoat, for example polyvinyl alcohol or ethylene vinyl alcohol copolymers, or from the presence of nonstick additives such as polyethylene or polyamide dispersions.
  • the binder of the top layer is selected from the group consisting of cellulose polymers, vinyl acetate-maleic acid copolymers, styrene-maleic acid copolymers, polyacrylic acids, polymethacrylic acids, hydroxyethylene polymers, polyethylene glycols, hydroxypropylene polymers, polyvinyl alcohols and Mixtures thereof.
  • the binder of the cover layer is preferably selected from the group consisting of polyvinyl alcohol (PVOH), ethylene vinyl alcohol copolymers, cellulose ethers, polyethylene oxide, starch, polyvinylpyrrolidone, polyacrylamide, polyacrylonitrile, polyvinylmethyl ether-maleic anhydride, styrene-maleic anhydride, hydroxyethylcellulose, methylcellulose, polyethylene glycols, carboxymethylcellulose , Polyacrylic acid salts, alginates, acrylamide copolymers, guar gum, casein, ethylene-maleic anhydride resins, polyethyleneimine, ethylhydroxyethylcellulose, ethylmethylcellulose, hydroxyethylmethylcellulose, and mixtures thereof.
  • Polyvinyl alcohol is particularly preferred as the binder of the topcoat.
  • the cover layer comprises at least one reinforcing filler, and / or at least one hydrophilic filler, and / or at least one anti-adhesive, and / or at least one wetting agent, and / or at least one dispersing agent, and / or at least one thickener.

  • the cover layer has non-stick properties. These may for example result from the properties of the binder, for example polyvinyl alcohol or ethylene-vinyl alcohol copolymers, or from the presence of non-stick additives, such as polyethylene or polyamide dispersions.
